摘要

Improvements introduced in the manufacture of flexible conductive tubes, according to which the tube is constituted by a cylindrical conduit of suitable ductile material, which presents in its wall a transverse corrugation, which runs uniformly and successively throughout the tubular length, determining a continuation of rings parallel and equidistant from each other, which have the equivalence of the contour of a half-round, and whose space of separation is smaller than the diameter of the curve of that one, thus allowing its adaptation to any curvature.
